Detailed Description
This class represents keyword selectors as used when forming (for example) subroutine calls or functor instantiations.
Since the right hand side of a keyword selector can be an expression or a type, depending on the context it appears in, we define two corresponding kinds of selectors. isTypeSelector returns true if its right-hand-side names a type. isExprSelector returns true if its right-hand-side denotes an expression. Several accessors are provided to retrieve the RHS as the needed type.
This class is a miscellaneous member of the AST hierarchy, as it does not belong to any one of its main branches (Type, Decl, Expr). This is a transient node used by the type checker to encapsulate a keyword selection, and does not appear in the final AST.
